Screw-on rubber feet and threaded rubber bumpers: Essentra SOF / BF series and Ganter GN 352.1 / 352.2 (452) sizes, thread, load — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/screw-on-rubber-feet-and-bumpers/ (sheet CC BY 4.0) Basis: Essentra's screw-on feet product pages and Ganter's GN 352.1 / 352.2 sheets (JW Winco copies) Catalog version: 2026-10-20 Sizes: see table below - Two kinds of rubber feet that fasten with a screw: (1) screw-on feet, a rubber or ABS foot with a clearance hole you drive a screw through (Essentra SOF- and BF- series; sizes as printed by Essentra, millimetres and inches agree on all nine), and (2) Ganter GN 352.1 / 452.1 (threaded stud) and GN 352.2 / 452.2 (tapped insert) rubber mounts, which are used as feet, bumpers, end stops and vibration mounts (zinc-plated steel cover plate for 352, stainless 1.4301 for 452; natural rubber, black, vulcanised to the plate; Shore A 55 ± 5 standard, 40 and 70 on request). - Essentra: 'screw hole diameter' is the figure Essentra prints in its table and 'inside diameter' (0.315 / 0.343 in) a second column on the rubber feet; the sources read do not define whether the hole is a countersink or the bore, so the table repeats the labels. The base diameters come in two forms on Essentra's pages (the product-attribute and the heading values differ in the third decimal: 0.689 vs 0.69 in for SOF-15140, etc.); the table uses the attribute values. The two pages agree on every height and diameter to 0.01 in; one page lists the rubber feet as neoprene, the other as 'rubber'. - GN 352.1 / 352.2: the tables are printed in inches for the thread (1/4-20, 5/16-18, 3/8-16) with d1 and h in millimetres (and inch values in brackets); metric-thread versions exist (e.g. GN 352-10-10-M4-E-55 is listed) but were not tabled. The two sheets disagree between each other on which d1 × h × thread combinations exist, so they are shown as separate row groups: stud version 8 rows (25 × 13 to 51 × 41), tapped version 8 rows. 'l' (stud length) and 's' (cover plate thickness) are Ganter's letters; 't' is the tapped depth. Spring rate (lbf/in) is on the sheets and is not repeated here. Rubber-metal mounts of the 351 / 451 series are on their own page. - Numbers only: the foot profile (dome, stepped base, counterbore) is not published as numbers, so no file is made. part type base or rubber Ø d1, mm height h, mm screw hole / thread material max load / deflection (GN 352 only) Essentra SOF-15129 screw-on foot 16 (0.630 in) 7.1 (0.280 in) screw hole Ø.310 in rubber (neoprene) — Essentra SOF-15125 screw-on foot 19.1 (0.750 in) 11.5 (0.453 in) screw hole Ø.400 in rubber (neoprene) — Essentra SOF-15140 screw-on foot 17.5 (0.689 in) 9.5 (0.374 in) screw hole Ø.310 in;
